PMR has Dunn a little above average for a leftfielder, above such players as Shannon Stewart, Jason Bay, and Todd Hollandsworth. He's always had relatively good speed for a guy his stature, and obviously he's not going to drop many more balls that hit him in the glove. He'll never win any gold gloves for sure, but he's far from a fish out of water in LF. I have never been a big fan of defensive metrics (and I am a big fan of offensive metrics). I have watched a lot of Adam Dunn, and I love him at the plate. Having said that, there is no way in Hades I buy that he is even an average defender in the OF. Better than Stewart and Hollandsworth? Not in this reality. He is slow and awkward. He doesn't get to many balls. All you have to do is watch him play, it is self evident. He is serviceable at best.
